Sword and shield is mostly for full tanks, if that’s gonna be your general play style.
You could try:
I’d drop Concentrate from this build though and go Gung Ho x5. Concentrate becomes obsolete as Gung Ho scales percentage wise where as Concentrate is just a flat buff. Someone else experienced in shields could probably tell you more opinions here. You will lose some damage as Fencer using a Shield, but hey, the damage will still be great. It’s not as huge of a deal as some have made it out to be, but it is still a thing. The reason Fencer is a good choice Rank 6 & 7 is because they have Evasion skills that at level 10 on just 1 gives an extra 100% Evasion.
Pretty much anything with Rodelero 2 is a good idea for tanks, they are one of the only classes that have a skill that helps with magical damage.
Now if you don’t want to be a tank
A very good spear wielding build. You could opt to take C2 Dopple instead of Dragoon if you wanted, they are very popular for Deeds of Valor and Cyclone. However fair warning DPS is some what gimped right now, but like all DPS swordies, you can wait for the incoming balances they have said they will do. When they will come is a question we’re all asking.
As for Highlander if you really like that class, it can fit into a lot of DPS builds. I really don’t think taking it in your last ranks is the best of ideas, you will lose a lot of damage as later ranking classes deal more. Someone from IMC has also stated they want early rank classes to phase out damage wise, so it’s always best to think in terms of utility.
Have a looksie and see what else tickles your fancy. kToS got some buffs on there for this class, but they have said we probably will not get them here.
